<p class="MsoNormal"><span lang="EN-US">Last IRC meeting, I heard that you are currently working on the HA on CDH and HDP, by chance that we just raise a bp about HA, so do you have any bp or spec about this topic? I think it’s interesting about this topic,
we can have some discussion.<u></u><u></u></span></p>
